We spent 20 days in Hostal Beni which were one of our best In Bolivia. The hostel is combination between hostel and hotel, with air con rooms or fan depends on your preferences. Our room was double with private bathroom and right on the Rurrenabaque river with stunning view.
Since we stayed for 20 days we took discounted price with 10% off, which is not bad on the overall calculation.
Rurrenabaque is a small town and the hostel is right in the middle of everything, restaurants and shops are in walking distance and the market is 5 minutes walk from the hostel.
Rooms are clean and the maid will clean it for you also upon request, there is TV cable but no internet which was the only downside of the place, but this is the case in most of the hostels. No hammock but the are place to put yours if you have one.
The hostel also includes a kitchen for your use but you will have to bring your own kitchenettes.
Hope this was helpful.
